10 Best Cordless Angle Grinders 2025 in the United States

The DEWALT 20V MAX Angle Grinder (DCG413B) is designed for those who need a reliable, cordless tool for grinding tasks. Its brushless motor enhances its durability and eliminates the need for maintenance associated with traditional motors. Users will appreciate the powerful performance, with a maximum rotational speed of 3450 RPM, making it effective for various grinding applications. Weighing only 3.75 pounds, this grinder is relatively lightweight, which aids in maneuverability and reduces user fatigue during extended use.

Safety features stand out with this model, particularly the brake that stops the wheel in two seconds or less, providing peace of mind when working on projects. The kickback brake provides an additional layer of safety by quickly shutting the grinder off if it senses a pinch or bind-up, minimizing the risk of accidents. Moreover, the E-Switch Protection ensures that the tool won't restart unexpectedly after a power outage, which is a crucial feature for maintaining user safety.

The DEWALT 20V MAX Angle Grinder is sold as a tool only, meaning you will need to purchase the battery separately. This could be a disadvantage for those new to cordless tools who might expect a complete package. Additionally, while the 20V battery is powerful, users may find themselves needing extra batteries for longer projects, which can add to the overall cost.

This model is well-suited for both DIY enthusiasts and professionals looking for a robust and safe cordless tool. Its safety features, lightweight design, and powerful brushless motor are significant advantages, while the lack of a battery in the package is a consideration for potential buyers. If you're looking for a dependable angle grinder that prioritizes safety and performance, this model is certainly worth considering.

It operates on an 18V battery, which is compatible with all M18 batteries, providing flexibility for users who already own Milwaukee tools.

The anti-vibration side handle is another plus, contributing to user comfort, especially during prolonged use.

However, there are a couple of considerations. The grinder is sold as a tool only, meaning you will need to purchase the battery separately if you don’t already have one. This can add to the initial cost for new users. Also, while it is relatively lightweight at around 5 pounds, some users may still find it a bit bulky for extended overhead work. In terms of ergonomics, its compact design helps, but users looking for a more maneuverable option may want to try out other models. The 5-year warranty is a reassuring factor, indicating Milwaukee's confidence in the product's durability.

Additionally, the Power Loss Reset feature is useful as it prevents accidental restarts after a power disruption, which is a great safety measure.

DEWALT tools are generally well-balanced and ergonomic, making them comfortable to use for extended periods. The 4-1/2-inch disc size is standard and versatile for various applications. The slide switch is a common feature that offers ease of use. However, it’s important to note that the tool is sold without the battery and charger, which means additional costs if you don’t already own compatible DEWALT 20V batteries. For DIY enthusiasts or professionals looking for a durable and safe cordless angle grinder, this model is worth considering.
